Inerting, blanketing and sparging

Inerting, blanketing, and sparging, are three common ways to combat oxidation, which occurs when moisture and oxygen contaminate the empty headspace around a product. Replacing the atmospheric oxygen with high-purity nitrogen fills the empty headspace with a dry, inert gas.



Our wide range of equipment is designed to safely deliver industrial gases to your instrument. Air Liquide’s VESTAL™ system is a customized nitrogen inerting and blanketing solution that supports product quality and safety by keeping out oxygen and moisture.


ALIGAL™ is Air Liquide's premier brand for food and beverage gases and equipment. ALIGALTM solutions can be customized to meet your quality, hygiene and operational requirements.
